下颌升支取骨在颌面部骨移植中的应用

Application of the mandibular ramus as a donor site for alveolar reconstruction

下颌升支作为临床较为常见的口内供骨区,可以有效地改善因各种原因导致的颌面部中小型牙槽骨缺损。本文根据下颌升支骨的解剖及特点,就其临床接受度、潜在供骨量及术后反应等进行了讨论,并简述了下颌升支二次供骨的可能性及减少术后不良反应的措施。

As a common intraoral bone donor site in clinic, mandibular ramus can effectively improve the small and medium-sized alveolar bone defects caused by various reasons in maxillofacial region. Based on the anatomy and characteristics of mandibular ramus, this paper discussed the clinical acceptability, potential bone supply and postoperative reaction, and the possibility of secondary bone supply of mandibular ramus and the measures to reduce postoperative adverse reactions were summarized.
